ENTERING SLX DATA
The Site and Location Cross Reference (SLX) table captures the spatial and hydrogeologic flow relationships existing between a site, and locations associated to it. These relationships are very important to a wide range of environmental activities such as: groundwater modeling and contaminant flow path studies, and numerous GIS and graphical data presentation applications. The Geohydrologic Flow Classification (GFCCODE) field exists to indicate whether the hydraulic flow at a location is up, down, or cross gradient to its associated site. The field Site Proximity Code (SPRCODE) exists to indicate whether a location lies within or is outside site boundaries, or whether the location is serving as background for the site.
GFCCODE Definition
U A location positioned up-gradient hydrologically from the contaminant source.
D A location positioned down-gradient hydrologically from the contaminant source.
C A location positioned cross-gradient hydrologically from the contaminant source.
Z Not applicable, site is not associated with or is not in close proximity to a groundwater formation.
SPRCODE Definition
O On-site
E Off-site
B Background by positioning in an area unaffected by the contaminant source.
